In this case, you can understand the bank's policies, choose the appropriate time, and consider the repayment cycle.

1. Understand bank policies: Different banks may have different bill date modification regulations. Before considering changing the statement date, first understand your credit card's bank policy, including the time allowed for changes, the number of changes, and other possible conditions.

2. Choose a suitable time: The bank will allow you to choose a suitable date as the billing day in each billing cycle. Choose a date that is most convenient for you to repay and manage your money. Your salary or other income comes in on a specific date, so setting the bill date after that date allows you to better organize your repayments.

3. Consider the repayment cycle: When modifying the bill date, the impact on the repayment cycle will be affected. Make sure you have enough time to repay after the bill date to avoid late penalties and interest. Also be careful not to set the bill date too close to the repayment date to avoid causing repayment pressure.
